UNITED STATES PATENT OFFICE 2 Claims.

This invention pertains to umbrellas and more particularly to acombined. notch and ferrule :for same.

Some arrangements employed for holding the cover of an umbrella in placerequire the use of a notch member, rosette washer and a ferrule andsewing to keep it in place. Sometimes the ieri'ule at the end of thestick is glued on. The disadvantages of this construction is that itloosens and becomes lost and allows the cover to come oir or get injuredin addition to allowing rain water to enter the end of the umbrella andstick and rot same.

lt is an object of this invention, to provide a new and improved ferruleunit that will be coinbined with the notch and perform additionalfunctions not secured in the use of them separately.

It is an additional object of the invention, to provide a new andimproved errule unit that will avoid one or more of the disadvantagesand limitations of the prior art.

Another object of the present invention is to provide a new and improvedierrule unit that will secure itself firmly to the stick of an umbrellaand hold the cover properly in place.

An additional object of this invention is to provide a new and improvedferrule notch unit that will be economical to make and install.

Other objects will become apparent as the in vention is more fully setforth.

In a particular form, illustrated as an example or this invention in thedrawings:

Figure l is a View of an umbrella in closed position, embodying thisinvention,

Figure 2 is an enlarged end view or Figure 1,

Figure 3 is an enlarged view of the combined notch and ferrule showingthe umbrella ribs, cover and rosette in section,

Figure 4 is a sectional view taken along line -fl of Figure 3,

Figure 5 is an end view of the sleeve, and

Figure 6 is a side elevation, partly in section, of the sleeve shown inFigure 5.

Similar reference characters refer to similar parts throughout thedrawings.

In the structure shown, an umbrella l is shown tted with a handle 8, andan umbrella stick i is formed with a slightly tapered end portion i l.

On this portion l I is slid a tapered ierruled thimf ble I2 whichincludes an integral rib notch ring i3 of conventional form forpivotally holding the ribs It. The cover I is sewed to the ribs in theordinary manner with its central portion i6 lapped over and open to slipover the ferrule thiinble l2 and rest on its notch ring it. A raisedring shoulder il is integrally formed peripherally around the body ofthe i'errule thimble i2 and spaced sufficiently from the upper surfaceit of the notch ring i3 to allow a hollow cylindrical sleeve it to fitand encompass it tightly and clamp the cover central portion i6. Thesection of the shoulder Il is as indicated, its under surface 2i beingflattened while its upper surface 22 is beveiled, while its depth is notover one-sixteenth or" an inch for ferrule thimble used on an ordinaryumbrella. The normal thickness oi' the walls of the thimble is aboutthree-sixteenths of an inch for a conventional plastic suitable for thedevice. The end portion 23 of the thimble termed the cap is closed-inand rounded. The interior surface of the thimble is preferably taperedto nt on to the tapered stick it tightly when pushed on. The thimble maybe pinned on the stick in the regular manner if desired. The exterior isgenerally straight. The sleeve i9 is bevelled interiorly at one end 2lito conform with the bevel 22, so that when pushed on, the sleeve willstretch resiliently as the sleeve passes over the shoulder Il andresiliently settles in the spacing provided for it, against the surface2i. The wall under this surface is compressed by the sleeve l when inplace as it is slightly less in diameter and clamps the stick moretightly so it cannot be removed. At the same time the rosette 2t andcover portion i5 are secured and held over the notch ring I3. The unitcombines parts usually separated into three distinct elements, into one,and adds the sleeve I9 for making it stronger and more eiective, inaddition to elimihating the tieing and stitching formerly required. Thecover also is held tightly in place and is kept taut and leak proof atthe end and strengthens the entire umbrella in a more substantial manener than has formerly been possible.

While but one general form of the invention is shown in the drawings anddescribed in the speciications, it is not desired to limit thisapplication for patent to this particular form or in any other wayotherwise than limited by the scope thereof, as it is appreciated thatother forms of construction could be made that would use the sameprinciples and come within the scope of the appended claims.

Having thus described the invention, what is claimed is:

1. A combination thimble and ferrule unit of the class described to beused on umbrellas to fasten the cover, ribs and rosette to the stickwithout the aid of sewing and comprising a hollow ferrule closed at oneend and having a notch portion at the other end to support the umbrellaribs thereon, a raised shoulder on the outer surface of said ferrulenear the closed end thereof and a straight face running from saidshoulder to the notch, a resilient sleeve adapted to stretch over saidraised shoulder and to resiliently settle to its original size to clamptightly against said straight face.

2. A combined notch and ferrule unit for attachment to an umbrella stickand for holding the cover and ferrule Without sewing and gluing, saidferrule being closed at one end to prevent weather from entering, saidferrule having a notch portion integrally connected thereto forreceiving and holding umbrella ribs, said ferrule having a raisedportion near the closed end, the

balance of the ferrule being straight between the notch and said raisedportion, and a sleeve adapted to stretch by sliding over said raised portion and to return to its normal size to tightly grip the said straightface between the notch and raised portion.
